WEED'ER.

SPECIFICATION forming part of Letters Patent No. 727,304, dated May 12,1903.

Application filed February 3,1902. Serial No. 92.305. (No model.)

To all whom it may concern:

Be it known that I, FRED J. KELLY, a citi- Improvement inWeeders, ofwhich the following is a specification.

My invention relates to that class of weeders in which the frame of theweeder is carried on wheels and the weeder-teeth are lowered into theground or raised therefrom by a lever.

The objects of my improvement are to stiffen the bars carrying the teethof the weeder, so as to prevent up-and-down vibration of the extremityof the bars without in any manner interfering with. the freedom ofmovement or the adjustability of the weeder. I attain these objects bythe mechanism illustrated in the accompanying drawings, in which- Figure4 is a perspective view of the entire machine looking from the frontright-hand side. Fig. 5 is a vertical section taken through the bars Aand the upright sliding posts 0, the dotted lines showing the frame inits raised position. Fig. 1 is a detail of the bars A; Fig. 3, avertical section of the sliding postsO; and Fig. 2,-the bearingBflnwhich it slides.

Similar letters refer to similar parts throughout the several views.

In the drawings, M represents the weedertooth bars,which are constructedin the usual manner and to which are attached the teeth P. These, barsare connected to form the weeder-frame in the ordinary manner by bracesN. I is the tongue of the machine, which is preferably formed of twoparts joined together at one extremity and kept separated at the otherextremity by a crossbar G or other suitable device. Pivotally attachedto the tongue I at the point 0 is an auxiliary tongue H, also preferablyformed of two parts. The tongue H'is connected by the link Q to theweeder-tooth bars M and serves to support and steady them. A lever L isconnected by a link E to the tooth-bars for the purpose of raising andlowering them. All these parts of the construction are well known andform no part of my present invention, which consists in the peculiarconstrnction which I shall now describe.

Pivotally connected to one of the tooth-bars M by fastenings D are twoupright posts 0,

"Figs. 4 and 5, which slide through bearings or clips B, attached tothesides of the tongue I'and braces A, extending from the upper or:-tremity K of the posts 0 to the tooth-bars M, to which they are attachedby bolts passing through elongated holes J in the foot of the braces,the holes being elongated for purposes ofadjustment. The twobracesAandthe posts 0 thus form,in connection with thetoothbars M, twohalf-trusses. These half-trusses only need to have the upper extremitiesK of the posts 0 connected together to complete the trusses and make aconstruction of extraordinary rigidity; but since in operation it isnecessary to raise and lower the frame, and with it the posts 0 andbraces A, it is not advisable to join the upper extremities of the postsby a rigidbar. The same effect, however, is produced by the cross-bar G,which rigidly retains the two parts of the tongue I at a fixed distancefrom each other. The upright posts 0 slide freely and yet closelythrough the clips B, and therefore in any different position in whichthey maybe'placed, whether-raised, as shown by the dotted line in Fig.5, or lowered, as in the entire lines,

the truss structure is complete and the rigidity of the frame issecured, while still leaving an open space between the two upright postsabove the tongue.

What I claim, and desire to secure by Letters Patent, is

1. In combination with the tooth-bars of a weeder, upright postsattached at one end to said tooth-bars and diagonal braces connect-.

ing said tooth-bars with the other extremity of said posts,substantially as described.

2. In combination with the tooth-bars of a weeder, upright postsattached at oneend to said tooth-bars, diagonal braces connecting saidtooth-bars with the other extremity of said posts and clips adapted toreceive said upright posts, substantially as described.

3. In combination with tooth bars of a weeder, upright posts attached atone end to said tooth-bars, diagonal braces connecting said tooth-barswith the other extremity of said posts, clips adapted to receive saidupright posts and means for keeping said clips at a uniform distancefrom each other, sulost-antially as described.

4:. In combination with the tooth-bars of a weeder, upright postsattached at one end to said tooth'bars, diagonal braces connecting saidtooth-bars with the other extremity of said posts, a divided tongue anda cross-bar adapted to keep the parts of said tongue at a fixed distancefrom each other, substantially as described.

5. In combination with the tooth-bars of a weeder, upright postsattached at one end to said tooth-bars, diagonal braces connecting saidtooth-bars with the other extremity of said posts, clips adapted toreceive said upright posts, means for keeping said clips at a uniformdistance from each other and means for raising and lowering saidtooth-bars, substantially as described.

6. In combination with the tooth-bars of a weeder, upright postsconnected therewith and diagonal braces connecting the extremities ofsaid upright posts with said tooth-bars, said braces being furnishedWith an elongated opening at one extremity adapted to receive a bolt,substantially as described.
